Limited,London, England, a British company Application March 31, 1937, SerialNo. 134,064 In Great Britain April 2, 1936 4 Claims.

This invention relates to advertising devices and more particularly toadvertising devices in which the advertisements in the form of plates orcards are fed mechanically in succession to a position behind a viewingaperture in a cabinet and then pass beyond this aperture to be broughtback again to the viewing aperture.

The invention has of the cabinet, and a reciprocatory carriage by whichthe plates or cards are elevated and by which also the cards to beviewed may be controlled in their downward movement.

In the accompanying drawings illustrating one embodiment of theinvention Fig. 1 is a perspective View of the mechanism within a frameand without the cards or plates, Fig. 2 is a side view showing themechanism and cards in the frame and Fig.3 a detail to enlarged scale,while Fig. 4 is a front elevation showing one of the plates or cards foruse therewith.

Referring to the drawings, I denotes generally a framework disposedwithin or forming part of a suitable cabinet (not shown) which isprovided with glass panels constituting a pair of viewing windows behindwhich plates or cards 2 containing advertising matter may be displayed.Within the framework are provided guide tracks for the cards 2, suchtracks comprising at each side horizontal portions 3 located above theupper viewing window in the cabinet (not shown) along which horizontalportions the cards 2 may be pushed from back to front of the cabinet bysucceeding cards or plates or by mechanism; vertical track portions 4adjacent the front of the framework down which the cards 2 may travelinto a position in front of a lower viewing window (not shown), inclinedlower portions 5 down which the cards 2 may travel to the rear of thecabinet and rear upright vertical portions 6 in which the cards mayagain be raised to the horizontal portions 3 of the guide track.

For the purpose of elevating the card or plate 2 from the bottom of theguide tracks 5 to the horizontal tracks 3 there is provided a.reciprocating carriage.

a motor 1 which through reduction gearing 8 rotates a spindle 9 on whichis mounted a double armed lever In one end of which is provided with acounter-balance weight M the other end being connected by a connectingrod |2 to the reciprocating carriage. The carriage is constituted byvertical members |3 at each side of the framework and spaced crossmembers M. The cross members 4 are fitted with brackets |5 freelyembracing a bracing member H5 at the rear of the framework serving as aguide. The ends of the cross members l4 extend around the sides H of theframework to the front thereof and are formed at the front withrearwardly projecting lugs l8 which serve to control the cards in theirdownward movement in the guide tracks 4. The vertical members |3 of thecarriage are provided with hook shaped recesses I9 serving to engage thesupporting spindle 20 of a card 2 and raise it in the tracks 6 in theupward movement of such vertical members. The vertical members |3 arealso provided with lugs 2| having an inclined face 22 for a purposehereinafter explained. For co-operation with the recesses l9 and lugs 2|there are disposed on each side of the cabinet spring-pressed arms 23which normally close the upper ends of the tracks 6 but are moved by thelugs 2| or the ends of the supporting spindles 2!] to permit a card topass, the spring pressed arms 23 returning to close the tracks 6 againthus preventing a card raised from falling in the rear track 6 andensuring the delivery of the card 2 elevated by the carriage to thehorizontal portions 3 of the track.

The front ends of the horizontal guide tracks 3 are normally closed bymeans of pivoted guide bars 24 pivoted at 24a. and connected by a link25. The guide bars are adapted to be raised by the upper edge of thelugs l8 engaging therewith or as shown with the connecting link 25during the upward movement of the carriage.

In the position shown in Fig. 2 the carriage is at the lowest point inits travel and the recesses I9 in the vertical members |3 of thecarriage have just engaged the ends of the supporting spindle 20 of therearmost card 2 in the inclined portions of the guide tracks 5. Rotationof the spindle 9 by the electric motor 1 serves to rotate the doublearmed lever l0 and thus raise the carriage with the card 2 engaged bythe recesses |9.

When the carriage is approaching the limit of its upward movement, thatis, in the position shown in full lines in Fig. 3, the projecting lugs2| or the ends of the rods 20 carrying the cards 2 force back thespring-pressed levers 23 to allow the passage of the spindle of the card2 and after the carriage has raised the ends of the supporting spindle2B of the cards 2 to the level of the horizontal portions of the guidetrack 3 the levers 23 close the vertical portions 6 of the guide trackto prevent the card 2 from returning down the guide track. At the sametime the pivoted guide lever 28 is raised by the edge of the lug l8 topermit the passage of the foremost card 2 in the horizontal track 3 intothe vertical track 4.

When the carriage commences to descend from the position shown in chaindotted lines in Fig. 3 the inclined portions 22 of the lugs 2| serve topush forward the last card elevated and all the row of cards 2 in thehorizontal portions 3 of the guide track so that the foremost card isfree to pass to the vertical portion 4 of the guide track and fall intothis portion. In this position the spindle of the card 2 shown in chaindotted lines in Fig. 3 is supported in its downward movement by theupper lugs I8 and the card is steadied in its downward movement by thelower pair of the lugs l8 leaving the card finally in front of the lowerwindow with the spindle 2i] supporting the card 2 in the inclinedportion 5 of the guide track. The rearmost card in this guide track isnow engaged by the recesses IS in the vertical members 13 of thecarriage on the next upward movement of the carriage.

By providing viewing apertures just below the horizontal portion 3 andbelow the inclined portion 5 of the track the foremost card lying ineach of these tracks may be viewed.

It will be appreciated that with the construction described when theapparatus is in operation successive cards will be exposed for a timebehind one viewing window while the preceding card is behind the otherwindow.

In lieu of providing twoviewing windows one only may be provided.

The construction illustrated is eminently suitable for use for instancein the foyers of picture houses for successively displaying stills ofscenes from a film.

While one embodiment of the invention has been illustrated obviously thedetails of construction may be varied. I

Thus instead of the cross members l4 embracing the stay !6 the verticalmembers l3 of the carriage may be in the form of rods passing throughsuitable guiding apertures.

In lieu of providing the counterbalance weight II at one end of thedouble armed lever Ill the weight may be attached to a chain or the likepassing over a pulley at the top of the frame I, the other end of thechain being anchored to the movable carriage. The counterweight isallowed to reciprocate out of phase with the carriage in suitablevertical guides. I

In the embodiment illustrated in the drawings the motor is coupleddirectly to the reciprocating carriage but a clutch may be interposedbetween the motor and the carriage. Thus the motor may rotate an armnormally coupled to the arm provided to reciprocate the bridge by meansof a spring ball catch, but adapted to be uncoupled with the motor stillrunning in the event of the frame or carriage becoming jammed.

For the transfer of the cards from the front to the back of the cabinetatthe lower ends of the vertical guides in lieu of providing inclinedguide tracks along which the cards descend by gravity I may providehorizontal tracks and lugs or projections on the reciprocating carriageadapted, at the commencement of the upward movement of the carriage, tomove the cards along the lower horizontal portion of the track in muchthe same manner as described with reference to the horizontal tracks 3at the upper end of the framework.

The whole framework may be mounted within a suitable cabinet by means ofsprings attached to each corner of the framework and anchored to thecabinet.
